4bda59f88d deinterlace: greedy, improve quality 
scanlines->m1 = same line of the previous field
scanlines->t0 = line above of the current field
scanlines->b0 = line below of the current field
scanlines->mp = same line of the next field

Deinterlacing a field weaved frame:
When deinterlacing the top field, the next bottom field is available
(part of the same frame). but when deinterlacing the bottom field,
the next top field (part of the next frame) is not available and
scanlines->mp equals NULL.

In this case it's better to use greedy algorithm using the prevous field
(twice) rather then linear interpolation of the current field.

3257ee4374 deinterlace: Fix vfir 16-bit orc calculations 
memcpy works in bytes, but orc works in items, so given that the size
arguments is in bytes, we need to divide by the pixel stride.

d0fdfa76ae deinterlace: Clean up error handling in chain and _push_history 
- Consistently unref the chained buffer at the end of the chain
  function, if we're not handing it off to `gst_pad_push`. This avoids a
  few buffer leaks in the error paths in `_chain` and `_push_history`.
- When mapping the video frame fails, return a flow error instead of
  crashing.

b699feefee yadif.asm: Fix improper usage of LOAD macro 
LOAD macro relies in m7 being zero for interleaving purposes. Using LOAD
on the m7 register makes it interleave with its new content instead of
with 0.

The effect of this bug was bobbing on some static lines that appeared
over fast-moving content.

dc1ae0aaa0 deinterlace: greedyh: Use _plane in _packed, fix planar formats 
This greatly reduces code duplication. It also exposed the cause for
planar formats not being properly deinterlaced:

The planar path was missing the initial offset adjustment that the
packed path did to `L2` and `L2P` in the case of an even field, which
caused it to select the wrong weave lines every other field.

Add those offsets in `_plane`.
